BOX-COVERING MACHINE.

No. a ain.

To all whom it may concern.-

Be it known that I, CHARLES A. GARRETT, a citizen- (if the United States, residing at Philadelphia, State of Pennsylvania, have invented new and useful Improvements in Box-Covering Machines, of which the follow.- ing is a speci cation.

This invention relates to box-covering machines of the type shown and described in the a general way the operation of the machine and thenigive a detailed description of the i improvements sought to be covered and protected herein.

According to my invention paper boxes are covered with a single blank comprising a body portion having integral side and end flaps. The blank is first coated on one face with glue, and the bottom of the box is then' centered on the glued side of the body por-' tion of said blank,-Which causes thelatter to adhere thereto, this operation in the" resent instance being carried out by hand. he box with its blank attached to the bottom thereof is then placed upon a two-part separable form-block carried by a reciprocating plunger, which latter is caused to move up. and down between covering devices that-act to fold flaps of the covering-blankup against the sides and ends of the box and firmly aflix them thereto and then trick the ends of the flaps over the edgesof and down into the box.

carried out in substantia ly the order nam'ed,

These several ste s or operations are box-cover. This, tothelbest of my present Specification of Letters Patent. Application filed April 12,1905. Serial No. 265.152.

knowledge and beliefj has heretofore been done by hand only. By the use .of my improvements, however, such boxes may be covered by prior patented machines of the type referred .to in as expeditious and perfect a manner as is the ordinary box. This end I attain in a simple and convenient manner and without change in the fixed structure of the prior machines by the substitution of one interchangeable part for another, 'thus adapting the same machine for use in covering two distinct types of boxes.

In the present instance I have shown and described only one specific form of means for carrying'out the'objects and purposes of the invention; but I do not wish to be under-- stood'as limiting myself to this particular means, as it will be obvious that mbdifications thereof within the scopeof the append:

ed claims will readily suggest themselves without departing from the broad spirit of the invention;

Briefly and generically stated, the invention. comprises means for applying covering material to the walls of a box having an extension edge, means operating in advance of the first-named means to turn the covering material over and down upon the extension edge, and means-to operate said first and last named means in sequence.

In the specific form. of means herein shown for carrying out theobjects of theinvention I provide a different form of covering element or roller for the sides and ends of the box, the said element or roller being provided with a recessto receive the extension edge of the box. This recess may be of any preferred form suited to the 'urposes at hand. I have found, however, t at a marked im-' provement in the covering operation is atthis recess of a certain form withrelation-to the extension ed e of the box, as will be more clearly set forth ere inafter. I A further object of my invention is to provide means whereby the recess is returned to a properposition with relation to the plunger at the end of the covering operation and whereby the recess may be ad usted in proper relation to said plunger.

The invention has for its further objects to provide certain other novel features, all of which will be more clearly defined in the following detailed descri tion and then. pointed out in the appended c aims.

In the accompanying drawings,'which form a part hereof and in which like reference characters designate like parts, Figure 1 a broken vertical section of a portion-of a ma chine embodying my invention sufficient to i rollers in position with respect to the lunshow the construction of-the same. :Figs. 2,

3, and 4 show diagrammatically the difierent stages inrthe operation of covering a box by my improved machine. Fig. 5 is a broken plan view, partly in section, of one of the covering-rollers. Fig. 6 isan end-view of one of the ,rollers, showing the means for, adjusting the same. Fig.7 is-a plan view lof the-coveringger. .Fig. Sisavertical section throng the bearin ofthe covering-roller, showingthe.

metho of returning the same to position aftereach-covering o oration; and Fig. 9 is a perspective .view 0 an extension-edge box 1 and the blank for covering-the same.

In the classvof-machines to which this in vention applies, the mechanism for affixing the cover to the different side and end walls of the-box are substantially duplicates, and

.asthis invention relates moreparticularly to .such mechanism only one set of the said mechanism is shown, and the description in mer 'patent referred .toand arecplieferably the. top of theslides and support thecove'ring 6 5 affixing the'covering-blankto the sides and .and moves .with the four in number, one for each side of the box to be covered. Two arms 2, forming a yoke, extend forward and laterally upward from mechanism.

A covering element 3, comprising a roller in the present instance, is mounted in tilting or'pivoted bearings 4, so as to be-moved into and out of the path of movement ofthe box by a springractuated rock-shaft 5 and a link 6, and pivotally attached to aplate 7, fixed to the yoke, is a brush 8,; allasmore clearly described in the aforesaid patent. Below the rollers 3 arethe endttucki-inwings 9, and in a yet lower plane are located theend-covering elements, which are substantially duplieatesof-theside-covering elements, cornv .the box B, to which it is to be affixed. vIn

prisin brushes and rollers. v 15 esignatesthe laten, which sup' orts ox-to be covered, and whose horizontal section is of substantially the same size as that of the form-block 16.

All of the above mechanism is particularl described in the aforesaid patent, to which reference is made.

My specific improvement relates to the construction and mounting of the rollers for This plate is substantia lysimilar.

ends of the box and to the mechanism for actuating the same, and attention is called to numeral 3 designates the roller in its entirety, 10 a cut-away portion of the same, and 11 a sleeve of yielding material, as rubber, filling the cut-away portion. The platen 15 is provided at its upper end with an extension 14 ,of the same area as the bottom of the box tobe covered. The uncut-away segment of the roller is provided'with a longitudinal groove or recess of approximately the depth of the edge extension of the box and ofa width at Y the bottom equal to the thickness of the box extension plus the thickness of the platen extension. The bottom of the recess is formed on the are of a circle having the same center of .the recess is undercut, as shown at 13, at

platen extension is'in the horizontal lane through the center of the roller. the si e 13 presses onand is parallel with the upper surface of the box extension. The 0 posite wall 13" of the recess may be termed t e platenengaging wall, and this wallv flares out-' wardly" away from the undercut wall 13, as shown, so as to resent a face that may be readil engaged as it escends.

T e oint or ed e17 of the recess fits snugl in t ecorner o the extension and box si e. The rollers 3- are mountis provided on one end of the shaft outside the bearing, containing a spiral spring 19, one end of which is attached to the shaft and the 19 is for the urpose of returning the ro ler 3 to its origina position after each covering operation, and to'insure its stopping in the correct position the following mechanism is made use of: A sleeve or collar 20 is rigidly attached to the shaft by a screw 20, and said collar is provided with a tail 20 bearing against ain 20 on the casing 18. The 0 sitionof t e pin 20, and conse uentl tiiat of the recess, may be varied by t e fol owing mechanism: The casing 18 is provided with a prolongation 21 ,having thereon a curvilinear slot 22, within which is a screw-threaded bolt 23,- screwed intoa part of the bearing. By loosening the screw. 23 the casing 18 may be turned and the position of the pin 20 varied. In Fig. 9 is shown the covering-blank And the operation of the machinethe box B is placed upon the blank A and-both placed on the form-blocklfi'. The latter moves down and meets'theplaten 15, and together they descend astthe'brushes 8, which initially applies'tlie covering to the box sides. The p aten extension 14 engages the lower side of the recess, and the further descent of the plunger and platen tends to rotate the roller 3 on its axis. This rotation brings the upper Figs 2, 3, 4,5, 6, and-8,inwhichthereference.

Further rotation, of the roller brings the circular face against the side of the box, and the coveringpaper is rolled up smoothly against the side of the box. After the boxasses the roller the spring 19 returns therol er to its original position. Further descent .of the box brings it to theYedge-turn-in fingers or wings, which turn in the'stay-flaps a, and, the operation is com leted by the covering-roller- 10, similar The 0 eration of turning down the edges into the ox may be done by hand or by the mechanism described in Patent No. 691 ,329

before mentioned. a I 'It will be understood that there are as many. rollers 3 as there aresides' of the box to becovered.

It .will be understood from the foregoing that the covering rollers are removably mounted in their bearings, so that when it is desired to equip a machine such as shown and described in the hereinbefore-mentioned patent it is only necessary to remove the ordinary form of covering-roller and substitute therefor the rollers forming thesubject matter of this applica ion.

As before state I do not wish to be understood'as limiting myself to the particular form of mechanism herein shown and described, for, ,so far as I am. aware, I am the first to provide mechanism for doing extension-edge work and reserve to myselfthe right to all modifications of the invention falling Within the scope of the following claims.
